However, the scalability of Bitcoin is unsatisfactory: it has large energy consumption and uncompetitive performance. Consequently, designing scalable blockchains has garnered significant interest from both academia and industry. One avenue of exploration has involved replacing proof-of-work with more energy-efficient alternatives, such as proof-of-stake and proof-of-space. However, the security of these alternative systems remain poorly understood. Concurrently, several emerging proof-of-work blockchain protocols employ a “parallel-chain” architecture to scale performance, where instead of a single chain, multiple chains operate in parallel and are subsequently aggregated.

One promising approach involves the fungible combination of various consensus mechanisms, resources, or blockchains. Fungibility is an essential attribute of these combinations, as it ensures that the system’s security is not solely dependent on one single consensus mechanism, resource, or blockchain. In this dissertation, we conduct a thorough study of the challenges involved in designing scalable and fungible blockchain consensus via proof of resource.
